Accidental first kiss by a female friend in a swimming pool when I was 15, a few weeks before my long-distance boyfriend was going to visit for the first time. We were trying to "air kiss" and missed because it was a wave pool and we got splashed at the wrong moment.

First official kiss, with the long-distance boyfriend a few weeks later, on the porch swing. He asked first, and it was very sweet and romantic, except I had onion breath because I was working at a pizza place, and the only dinner I had managed to grab had onions on it.
